Mt. Igneus

Mt. Igneus is a volcano located on Route 6, behind Brimber City. It is where the Legendary Pokémon Groudon is located. When the player explores this volcano for the first time, the player must expel Team Eclipse because the villainous team robbed the Red Orb from Brimber Gym and headed here to wake Groudon.

Summit Crater
The summit crater of Mt. Igneus is where the first real showdown of player and Team Eclipse takes place. Eclipse Admin Harry places the Red Orb to awaken Groudon despite being defeated by player, only to be scared off by the enraged Legendary Pokémon when his mask is blown off by only a roar from Groudon. Gym Leader Sebastian comes to the player's rescue immediately afterwards, quickly calming Groudon and averting the crisis of volcanic eruption.

Lava Pool
There is a tunnel that leads to a lava pool, which can only be bypassed when Rock Climb is acquired. A hiker is there for player to battle, and he is also available for rematch.

Pokémon
All Pokémon are encountered at Lv.9-11.

Trainers
Note: Trainers marked with a star symbol (*) are available for rematches.

Trivia

 * As half of the wild Pokémon gives Special Attack Effort Values upon defeat (with Heatmor giving 2), and Hiker Darrel's Pokémon gives 1 Sp. Atk EV each, Mt. Igneus is ideal for player to enhance his or her Pokémon's Sp. Atk stat.
 * The music in Mt. Igneus is based on Hoenn Route 113 from the core series game Pokémon Ruby, Sapphire and Emerald.
